SPECIFICATION forming part of Letters Patent No. 269,856, dated January 2, 1883.-

Applicntion filed January 19, 1882.

.To all whom it may concern:

Be it known that l,- ALFRED B. HoLooMBE, a citizen of the United States, residing at Lambertville, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in Wood-Splitting" Machines, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to machines for splitting wood; and it consistsin certain improvements in the construction of the same, as hereinafter shown and described.

In the accompanying drawings. Figure 1 represents a side view of a wood-splitting machine having my improvements. Fig. 2 is a View of the front end of the same. Figs. 3 and 4 represent detached views of certain details.

A designates the upright posts of the main frame, and Bthe foundation or base-timber.

0 indicates the cross-pieces at the top, on which are placed the boxes a of the shaft D. The frame is strengthened by means of the vertical rods, Z), which pass through the boxes a and horizontal pieces 0 to the foundation B, the rods being secured at their extremities and the parts mentioned being held firmly in place.

E represents a fly-wheel on the forward end of the shaft D, said wheel having a crank connection at m with one end of a pitman, F. The lower end of said pitman is coupled. as shown, to a sliding head, G, which carries a blade or ax, c, and moves up and down between the guides d, which are made fast to the frame, as shown. The ax o is removably secured to the head G by a dovetail connection, 0, so that the ax is readily attached and detached as desired.

The guides d are of peculiar construction, projecting forward and also turning somewhat inward, so that the ax passes between them in its upward and downward movement, ample room being left for such purpose. The guides therefore serve the double function of guides for the ax and strippers for the wood, so that when a block of wood is not entirely split, and

(No model.)

adheres to the ax as it moves upward, the

head G, so that when the desceudingax strikes,

the block of wood the coupling points of the pitman are directly over the point where the ax enters the wood.

The elevation of the block of wood to be split is regulated by means of the plates 9, provided with projections s on their lower sides and apertures to receive such projections. These plates are placed one above another under the ax, the projections s enteringthe holes in the plate next below, and the plates are thus held firmly in place. The block to be splitis then placed on the foundation thus formed, the required number of plates being used to raise the block to the proper height to receive the stroke. Power is applied to the machine usually by means of beltiugpassing over the wheel H on the shaft 1). The main frame is held firmly in position by means of the rods b and vibration thereof prevented.

I claim- 1. In combination with the frame of a woodsplitting machine, the guides of the slitting head which carries the ax. said guides having grooves receiving projections on the ax-head and being formed, substantially as shown, to project forward and close toward the line of movement of the ax for the purpose of preventing the wood adhering thereto, as herein set forth.

2.111 a wood-splitting, machine, the plates g, each having apertures as described and provided with projections s, adapted to extend 8 into the apertures of the next plate, substantially as set forth, for the purpose specified.

In testimony whereof I have atfixed my signature in presence of two witnesses.
